To albwhom, it may concern.-

Be it known that we, GEORGE I. KING and JOHN H. FRANK, citizens of the United States, residing at Middletown, Pennsylvania, have invented a certain new and useful Improvement in Underframing for Railway-Oars, of which the following is a full, clear, and exact description, such as will enable othersskilled in the art to which it appertains to make and to use the same, reference being had to the accompanying drawings, forming part of this specification, in which 5 Figure lisa plan view of our improved uuderframe. Fig. 2 is a longitudinal sectional view. Fig. 3 isa side 'elevational view. Fig.

4 is a front elevational view. Fig. 5 is a crosssectional view of one side of the bolster, and Fig. 6 is across-sectional view of one side of the intermediate floor-support.

improvement in underframes for railwaycars, being designed particularly for use in connectionwith street-railway cars of that type wherein there is a platform at each end of the body. I

The objects of the invention are to simplify the construction of underframes of this character and to produce a strong anddura'ble underframe which may be used with various types of cars and which is peculiarly adapted for street-cars.

In the drawings, 1 indicates the side sills, which are preferably in the form of channels, with their flanges presented inwardly. 5 2 indicates the center sills, preferably in the form of channels, with their flanges present ed outwardly. 3 is the end sill in the form of a channel whose flanges are presented outwardly. All of these sills may be of the same 40 vertical height. 7

The bolster or transom consists of a fillerblock 4, which may be a casting, with an appropriate opening for the king-bolt, and side web members 5,'secured to the side and'center sills by appropriate connections and to.

top and bottom cover-plates 6 and 7 by angle-irons arranged on each side and at the top and bottom edges thereof.

Sindicates spacing-blocks between the center sills, which are preferably of pressed steel,

This invention relates to a new and usefull although malleable castings may be employed, and 9 indicates angles lying in the transverse planes of the blocks 8, which angles serve as tie-rods and also afiord supports for the longitudinal wooden sills or furringstrips.

10indicates connection-plates .at the corners of the uuderframe', to which are riveted oblique braces 11, whose inner ends are secured to the top cover-plate of the bolster. 60, These connection plates 10 extend beyond the end sill and have attached thereto the ends of a bent platform-sill 12, which is preferably in the form of an angle, with its horizontal flange presented inwardly. The ends of this platform-sill in addition to being riveted to the connection-plates 10 are also secured to'corner connection-angles 13, which in turn are riveted to the end sill, the rivets which are employed for securing these corner connection-plates to the web of the end sill also serving to attach one leg of a corner connection-angle'14 at the junction of the end sill and side sill. Oounection-plates15 are employed at points intermediate the ends of the end sill, to which are secured oblique braces 16, diverging outwardly to the curved corner portions of the platform-sill, while braces 17 converge at their outer ends and are secured to a connection-plate 18, riveted ap- 8o proximately at the central portion of the plat-v form-sill. The braces 16 and 17 are preferably in the form of angles, the lattersupporting at their outer ends a carry-arm 19 for the draw-bar. This carry-arm has upwardly-flaring side members, between which is riveted a U-shaped spacing-block 20. y We have not deemed it'necessary herein to show any portion of the body of the car, the abutment-angles for the wooden end sill filler, 0 nor step-irons, asthey may be constructed and arranged according to the tastes of the builder.

From our improved construction it will be observed that the underframe is made up, 5 essentially, of commercially-rolled material, the platform-underframe being applied in position practically as a separate feature, the only elements common to the main underframingand platform-underframingbeingthe I00 connection-plates, which project outwardly beyond the end sill, to which the members of the platform-underframing are riveted, and the rivets which secure the corner con nectionangles at the ends of the end sill in position. By the arrangement of these corner connection-angles the platform-sill is inset with respect to the side walls of the main underframing, which is desirable.

We are aware that minor changes in the construction, arrangement, and combination of the several parts of our device can be made and substituted for those herein shown and described without in the least departing from the nature and principle of our invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. Thecombination withamainunderframing for cars, of a platform-underframing comprising a curved or bent sill having its ends connected to the main underframing, and braces for said curved sill; substantially as described.

2. The combination with a main underfram ing for cars, of a platform-underframing comprising a curved or bent angle Whose ends are connected to the corners of the main underframing and set in with respect to the side members of said main u'nderframing, and obliquely-disposed angles for bracing said plat form-sills; substantially as described.

3. The combination with a main underframing for cars, of cornerconnection-plates therefor which extend outwardly beyond the end sill, and a platform-underframing having a curved sill whose ends are connected to said corner connection-plates; substantially as de- .scribed.

4E. The combination with a main underframingforcars,ofaplatform-underframingwhose side members are riveted to the corner connotation-plates of the main underframing and to corner connection-angles whereby said side members of the platform-underframing are set in with respect to the side members of the main underframing; substantially as described.

5. The combination with a main underframing for cars, of connection-plates at and between the ends of the end sill, which connection-plates extend outwardly, a platform-underframing comprising a curved sill whose ends are bent and connected to the corner connection plates, and obliquely disposed braces connected to said curved sill and to said connection-plates intermediate the ends of the endsill; substantially as described.

6. The combination with a main underframing for cars, of aplatform-underfralning comprising a curved sill having its ends connected to the corners of the main underframing, obliquely-disposed braces for said curved sill, and a reinforced carry-arm depending from said braces; substantially as described.

7. The combination with a main underframing for cars, of a platform-underframing connected only to the end sill and to connectionplates carried by the end sill; substantially as described.

8. The combination with a main underframingincluding an end sill, of connection plates and angles attached to said end sill, and a platform-underframing attached to said connection plates and angles; substantially as described.

In testimony whereof we hereunto aflix our signatures, in the presence of two witnesses, this 9th day of September, 1903.
